Answer 1

With one of the planet's lowest population densities, the people of the Sahara can seem afloat in vast seas of sand. Blue-robed Tuaregs still run salt caravans and herd goat, sheep and camels. Moors farm date palms. An oasis in the Sahara can vary in size from about 2.5 acres for a tiny village to larger farm lands. At its hub is water, often in the form of natural springs, artesian wells or entire irrigation systems. About 75 percent of the Sahara's population live in oases, which make up only a tiny 800 square miles of the desert's vast sea of sand and gravel. The date palm is most characteristic of the vegetation that flourishes there. Other typical food sources grown in Saharan oases include figs, peaches, citrus fruits, wheat and barley.

According to the passage, why do most of the people of the Sahara live in oases?

because the Tuaregs build the oases
because the cities are too polluted
because people are moving off of farms
because oases have sources of water
